This invention relates to im rovements in stripping means for flatwor ironers; to prevent the work being ironed from adhering to find becoming wrapped around the ironing '8' re s.

circle the set of ironing rolls with a transversely spaced series of Ion 'tudinally extendin endless strings, rib us or tapes,

1 which ave stripped the work from the rolls in a satisfactory manner but have marred the finished appearance of the work by leaving therein conspicuous impressions, particularly the impressions left bg the strings and the selvaged or otherwise nished edges of the tapes and ribbons.

It is therefore the general object of the present invention to provide improved stripping means for flatwork ironers, which means effectively strips the work being ironed from the ironing rolls but does not leave therein any impressions whatsoever. The strippin means here provided comprises a series 0 endless tapes having longitudinal edge portime of gradually decreasing thickness. Specifically, the present tapes are made of the same fabric material as the ironing roll covers and have frayed longitudinal edge portions. As the result of the articular material of whichthe'y are ma e and of their frayed portions, these tapes leave no impressions whatsoever in the work, so that the finished appearance thereof is in no way marred by the use of these tapes.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The invention will be readily understood from the following description taken in con-. nection with the accompanying. drawings, in which Fig. 1 is a side elevation of a flatwork ironer-with the present strippingtapes applied thereto, said ironer being shown. in dash dot'lines; Fig. 2 is a plan view of the ironer andthe present stripping tapes, the vironer being shown in dash-dot lines; Fig.

3 is a plan view of one of the spring take-up devices used with the present stripping tapes;

Fig. 4 is a vertical sectional view of said take- 9 up device, the view being on the line H, of the same fa Heretofore, it has been customary to en-' Fig. 3; Fig. 5 is a detail sectional view of one of the present stripping tapes and the spring take-up device therefor the view being on the hue -5, Fig. 3; and Fi s. 6 and 7 are respectlvely a plan view an a cross sectional view of one of the present strippin tapes.

The ironing machine illustrate in .the drawmgs is of the conventional type and therefore includes a frame 1 having mounted thereon a set of heated ironing chests 2. Cooperatin with said chests and mounted in suitable earings in said frame are a set of ironing rolls 3, a six-roll ironer bein here shown. These rolls are provided witl suitable padding (not shown) comprisin inner padding material of cork, springsor file like and an outer cover cloth of canvas, muslin, or the like, as is usual. For applying pressure between the ironing rolls and the ironing chests for the ironing operation, two pressure bars 4 are provided, one at each side of the machine for cooperation with the roll ends.

The work to be ironed is fed through the machine by the rotation of the ironing rolls and it has been found necessary, or at. least desirable, to provide means for preventing.

the work from adhering to and becoming wrapped around said rolls. Heretofore, strings, ribbons and tapes have been used for this purpose, and while they have stripped the work from the rolls in a satisfactory manner they have marred the finished appearance of the work by leaving therein obj ectionable impressions, the impressions formed by the strings and the selvaged or otherwise finished edges of the ribbons. and tapes being particularly conspicuous.

The present im roved stripping means com rises a series 0 endless tapes 6 which encirc e the-ironin rolls, being suitably spaced alon their lengt as clearly indicated in Fig. 2; S aid tapes havemiddle body portions 7 of substantially uniform thickness and longitudinal edge portions 8 'of gradually decreasing thickness toward their edges. The material of which'the tapes are madeispreferably of the same fabric character as the ironing roll cover cloths and the work being ironed. The particular tapes here illustrated are made ric material as the cover cloths of the ironing rolls, that is, of canvas, muslin or the like, and have their lon itudinal edge portions frayed, as best shown in Figs. 6 and As the result of the material of which they are made, and of their frayed edges',the

' as indicated in Fig. 1, suitable take-up de-' 7,

vices are provided therefor, as is usual. In the present embodiment of the invention, a spring take-up device is provided for each tape and as the several take-up devices are of identical construction, a description of one will suilice for all.

Mounted on the forward end of each of the. two pressure 'bars dis a bracket 12 and in.

these two brackets are rigidly mounted the ends of a shaft 13. Mounted on this shaft, in proper spaced relation, are the. several take.- up devices,.one for each tape.

Each take-up device is made of a one piece heavy wire bent to provide an anchoring end portion, a tape-supporting end portion and an intermediate portion 18 connecting said end portions. The anchoring end portion is formedinto two eyes 19 and 20 loosely encirclin shaft 13 and joined by a bridge 21.

Suitably secured to said bridge is one end 22' of aspring 23 coiled around shaft 13 and hav-.

ing its other end 24 suitably such as thereof secured thereto, b being anchored in the aperture 25 {Fig 5). The secur'ement of the in one direction of the take-up device along said shaft, and to prevent movement of the take-np-device along the: shaft in the other direction, acotter or other pin 27 extends through. 'saidshaft and engages. the spring end .22, as best shown in Fig. 3.

The intermediate connecting portion 18 of the .wire extends directly forwardlyfrom the top of eye 19 of the. anchoring end rtion andis therefore, substantially nor-ma thereto. e tape-su porting wire end portion 30 extends perpen cularly from the forward end of connectin wire portion IB -Ind'therefore 1s substan y parallel with the anchoring wire end portion. Rotatahly' on. the tape-supporting wireend portion is a roller 32 having an annular tapes-receiving groove 33' of concave shape in cross section,

said shape preventing folding of the frayed tape edge portions 8, This roller is prevented from escaping at side by the connect-ing spring end 24'to shaft 13 prevents: movement wire portion 18 and at the other side by a,

cotter pin 34 extending-through the wire end. The strippin tapes 6 pass, therefore, at the forward en end ironing roll 3a and the rollers 32 of the take-up devices. At the rear end of the ma chine, the tapes pass around the end ironing roll 36 and the stationary bar 35 carried by brackets 36 mounted by means of pins 37 on the rear ends of the pressure bars What I claim is:

1. In an ironing machine of the type hav ing an ironing chest and a padded lromng 'roll cooperating therewith and between which chest and roll the work is passed for the ironing. operation, and means for strlpping the work being ironed from said roll and comprising a tape adapted to be passed through the machine with the work,-being interposed between thework and the ironing roll, said tape having a middle body portion of substantially uniform thickness and longitudinal edge portions of a thickness grad uallyv decreasing toward the outer edgesthereof. 1

2. In an ironing machine of they type having an ironing chest and a padded lronin roll cooperating therewith and between whic chest and roll the work is passed for'the ironing operation, and means for stripping of the machine around the the work being ironed from said roll and comprisin a fabric tape adapted to be passed through t e machine with the work, being interposed between the work and the ironing roll, said tape having a middle body portion of substantially uniform thickness and frayed longitudinal edge portions of ap preciable width.

3. In an ironing machine of the type having an ironing chest and an ironing roll cooperating therewith and between which chest and roll the work is passed for the ironing,

operation, said roll being padded and covered with a fabric cover cloth, and means for strip ping the work being ironed from said roll and comprising a tape adapted to be passed through the machine with the work, being interposed between the work and theironing roll, said. tape being made of the same fabric material-as said ,ironing roll cover cloth and having frayed longitudinal edge portions of appreciable width.

4. In an ironing machine of the type an ironing chest. and a paddedironi operating therewith and between w ich chest and roll the work is passed for the ironing operation, means for stripping the work being ironed. from said roll and comprising an endless fabric tape encircling said ironing A roll and having frayed edge portions of a preciable width, said. tape lying between t e work and the ironing roll and thus serv'in to prevent the. work from wrap ing aroun said roll, and a take-up device or said tape having a roller over which said tape we said roller having an annular tape receivin groove of concave shape in cross section, sai shape preventing folding of the frayed tape edge portions.

5, In an ironing machine of the type having an ironing chest and an ironing roll cooperating therewith and between which chest and roll the work is passed for the ironing operation, said roll beingpadded and covered with a stripping the work being ironed from said roll and comprising a tape adapted to be passed through the machine with the work,

' being interposed between the work and the ironing roll, said tape being made of a fabric material corresponding to the fabric material of the cover cloth of said ironing roll and having frayed longitudinal edge portions of appreciable width. p
